GS1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0637440 (GS1, HvGS1) on barley chromosome 7H encodes a protein with riboflavin kinase activity, FMN adenylyltransferase activity, and sugar-phosphatase activity, including sn-glycerol 3-phosphatase activity, and belongs to the HAD-like superfamily. The gene is associated with nitrogen utilization and response to nitrate, glycerol anabolism, leaf senescence, seed and root development, and salt stress response. It is linked to grain yield, grain filling period, and protein content. The encoded protein localizes to the cytosol, mitochondria, and plasmalemma. Studies of related genes in other species link the family to salt, osmotic, and oxidative stress tolerance, desiccation tolerance, and formaldehyde stress resistance, and to grain yield, grain protein content, spikelet number, panicle weight, and nitrogen recycling.
